ZMI No.20 power bank review
Power banks that claim to fast-charge laptops often fall short, but the ZMI No.20 delivers 100W output in a premium package. ZMI might not be a name you've heard of, but the brand is a key part of Mi (Xiaomi) and is well-known for making excellent, high-quality products. The No.20 is no exception, with a large 25,000 mAh (90 Wh) capacity, high-end components, and impressive multi-device charging capabilities. It’s one of the best power banks available, though it can sometimes be difficult to purchase in Australia and the US, and almost impossible to find in the UK. Amazon is often the best place to buy it, but keep in mind that it doesn't go on sale frequently.
